The court analyzed the impact of the policy exclusion barring coverage where one insured sued another. Gemini Ins. Co. v. Delos Ins. Co., 2012 Cal. App. LEXIS 1230 (Cal. Ct. App. Dec. 5, 2012).
Delos insured Bobby's, a restaurant, located in the Loch Lomond Marina, San Rafael, California. The landlord was Loch Lomond Marina. A fire at Bobby's caused damage to Loch Lomond's property. Another business, Arena Yacht, also suffered property damage from the fire. Loch Lomond was insured by Gemini for property damage.
Gemini paid Loch Lomond $288,259 and Arena Yacht $65,088 for the damage caused by the fire. Gemini then sued Bobby's for subrogation, alleging Bobby's negligence caused the fire. Delos defended Bobby's. The case settled. Bobby's and Gemini entered into a stipulated judgment for the total which Gemini had paid to its insureds. Delos paid $65,088 of the judgment, the amount Gemini had paid to Arena Yacht.
Gemini then sued Delos. Delos' policy did not provide coverage for any claim or suit brought by another insured. Loch Lomond was an additional insured under the policy. Delos therefore argued that it did not cover Bobby's on a claim by Loch Lomond for damage to Loch Lemond's property. Gemini contended Loch Lomond was not an insured under Bobby's Delos policy.
The trial court agrred with Gemini, finding that under the language of the Delos policy, including the additional insured endorsement, Loch Lomond was never an "insured" under the policy. Judgment was entered for Gemini in the amount of $288,259, the amount Gemini had to paid to Loch Lomond.
The Delos policy's Interinsured Claims and Suits Exclusion barred coverage for any insured against a claim or suit by another insured. The policy defined "insured" as "an organization other than a partnership, joint venture, or limited liability company." The additional insured endorsement listed Loch Lomond as an additional insured.
However, there was another relevant policy endorsement entitled "Additional Insured - Managers or Lessors of Premises." Under this endorsement, Loch Lomond was an additional insured only when it faced liability arising from Bobby's acts, undertaken in the course of Bobby's operations on the leased premises. No one had sought to hold Loch Lomond liable for the fire. Instead, in the underlying case, Loch Lomond sought to recover from Bobby's.
Therefore, the interinsured claims and suits exclusion did not apply and the trial court's judgment was affirmed.
